Fog Clearing Using Helicopter Downdrafts: A Numerical Model.

Abstract

A Numerical Model.Research and development technical rept.,Nordquist,Walter S. , Jr;ECOM-5527DA-1-T-061102-B-53-A1-T-061102-B-53-A-17*Fog, *Weather modification, Helicopters, Downwash, Mathematical models, Dissipation, Heat, Meteorological parameters, Feasibility studies, Computer programs, FORTRAN*Fog dispersal, Helicopter downwashA one-dimensional parameterized numerical model is presented which depicts the physical conditions attendant with the use of helicopter downdrafts for the creation of temporary clearings in fog. The results generated by the numerical model are compared to the data available from helicopter downdraft experiments. An example is given of the application of the model for investigation of the utility of the helicopter downdraft fog clearing technique for a particular set of meteorological conditions. (Author)
